Side-by-side comparison of two Model Context Protocol servers — install paths, tools, quality signals, and directory engagement so you can pick the right one for Claude, Cursor, and other MCP clients.
Unified API for AI agents — 180+ tools across geocoding, weather (NWS), climate stations (NOAA), earthquakes (USGS), tides (NOAA), points of interest (OpenStreetMap), patents (USPTO ODP), US case law (CourtListener / Free Law Project), Federal Register, Wikipedia, scientific papers (arXiv / PubMed / Semantic Scholar), AI summarize / translate / extract / screenshot / image-describe, image compression, DNS / WHOIS, crypto address-validate + EVM gas oracle, OFAC sanctions screening, US Census ACS demographics, airport / ZIP lookup. Sub-cent to a few cents per call in USDC on Base via x402 — no API keys, no signup. npx -y @2sio/mcp
Local proxy that collapses N downstream MCP servers into 4 meta-tools with progressive tool discovery (measured: 122 tools → 4, 28.6K tokens of definitions saved), compresses large tool outputs (HTML→Markdown, JSON structure summarization, base64 stripping — 60–95% measured on real pages/APIs) with full-output retrieval via readmore, and prints a per-session token-savings report. Security-relevant outputs are never silently compressed. Install: npx -y context-firewall --config config.json
